Real-cap user here.
I bought some realcaps just because they were cheap and added to the realism. I am now looking into midcaps (that is after I get my next pay).
Hicaps are generally not recommended because they rattle, you need to wind them (exception for the motorized winding ones), and it's usually banned in mil-sim games (and some skirmishes because they want to keep to the realism thing).
